摘要: Abstract It is important to study the falling-film pattern of a horizontal tube bundle in order set up heat and mass transfer model accurately. The simulated this paper. technique based on computational flow dynamics (CFD) for two-phase gas water. experimental results were used validate mathematical model. indicates that simulation accord with data well. show varies different rates. Under rates, it observes droplet, droplet-columnar, columnar, columnar-sheet sheet patterns. critical value 0.0125 kg/s between droplet 0.02 kg/s columnar sheet.
